Students were surveyed about their favorite colors one fourth of the students preferred red 1/8 of the students preferred blue, and3/5 of the remaining students preferred green. If 15 students prefer green how many students were surveyed
Answers
Answer 1
Answer:
Let us assume the total number of students surveyed = x Then Number of students preferring red = x/4 Number of students preferring blue = x/8 Then Number of students remaining = x - [(x/4) + (x/8)] =x - [(2x + x)/8) = x - (3x/8) = (8x - 3x)/8 = 5x/8 Number of students preferring the color green = (3/5) * (5x/8) = 3x/8 We also know that the total number of students preferring the color green is 15 So 3x/8 = 15 3x = 15 * 8 x = (15 * 8)/3 = 5 * 8 = 40 So in total 40 students were surveyed. I hope the procedure is clear to you.

Ben is 140cm tall. Mike is 1090mm tall. Who is taller? how much taller?
Answers
1 cm = 10 mm
Ben = 140 cm Mike = 1090/10 = 109 cm

Ben is taller by 31 cm or 310 mm
1090mm = 109cm Ben is taller.
A ride on the roller coaster costs 4 tickets while the boat ride only costs 3 tickets. Michael went on the two rides a total of 10 times and spent a total of 37 tickets Which equation is true?
Answers
Let x be the number of times that Michael rode on the roller coaster and let y be the number of times that he rode on the boat, then: x + y = 10 [because he went on the two rides a total of 10 times], and 4x + 3y = 37 [because a ride on a roller coaster costs 4 tickets and the boat ride costs 3 tickets and he spent a total of 37 tickets] From the first equation, 4x + 4y = 40 subtracting the second equation from the third equation gives: y = 3, and from the first equation x = 10 - y = 10 - 3 = 7 Therefore, Michael rode on the roller coaster 7 times and on the boat 3 times.
The answer is C. Hope this helps! :D
